I have not been receiving emails for subcribed threads since about this past Saturday. I checked my settings and I should be, and I checked my junk mail in case the address the mail is sent from had changed. No emails there. It just seems that I'm not being sent the emails despite opting in for them. I'm estimating it was Saturday that it stopped after I went to check the site Saturday morning (UK time) and noticed the site was down. When I asked in the Steam group chat, the replies indicated the site was down for maintenance. Could be just a coincidence, but worth mentioning in case it is related.
